## Conversion formula

The conversion factor from centimeters to millimeters is 10, which means that 1 centimeter is equal to 10 millimeters:

1 cm = 10 mm

To convert 8.2 centimeters into millimeters we have to multiply 8.2 by the conversion factor in order to get the length amount from centimeters to millimeters. We can also form a simple proportion to calculate the result:

1 cm → 10 mm

8.2 cm → L(mm)

Solve the above proportion to obtain the length L in millimeters:

L(mm) = 8.2 cm × 10 mm

L(mm) = 82 mm

The final result is:

8.2 cm → 82 mm

We conclude that 8.2 centimeters is equivalent to 82 millimeters:

8.2 centimeters = 82 millimeters
